DOWN-HOLE MOTOR SERIES
The BPM down-hole motor is a kind of drilling tools
developed for converting hydraulic energy into mechanical energy through
power section which is made up of a stator and a rotor. The motors are
usually divided into two kinds, single lobe (1/2) and multi lobes (N/N+1)
motors, according to the quantities of the lobes of the stator and rotor.
Generally speaking, for motors of the same length of rotor/stator section,
the more the lobes are, the higher the output torque is, vice versa. The
motors are usually used together with cone bits, diamond bits and so on
in drilling operation, such as directional and vertical drilling, horizontal
drilling, correcting deviation, coring, reaming, sidetracking, etc.
BPM down-hole motors may also be equipped with extended power section.
Comparing with common motors, they are greatly increased in output torque
and power, which help to increase penetration rate markedly. The BPM down-hole
motors enjoy high prestige in the North America market because of their
prominent performance and more than thousand hours working life.
Down-hole motor adjustable bent housing is optional. It can easily adjust
the bent angle from 0 to 3 degrees (between 0 to 3 degrees) in the rig
floor without shim. The angle is directly pointed to the high side of
tool face.
BPM down-hole motor has independent intellectual property rights like anti-friction
connecting rod. It obviously improves the capacity of the motor and also
increased the running time.
Also BPM owns patented oil-lubricated sealed bearing assembly, which improves
its load and working time without interruption. The new type drive shaft
that designed for long life down-hole motor can resist shock, vibration
and high load; meets the requirement of complex drilling. The housing
of the drive shaft can match a stabilizer with different models and sizes.
BPM has been the first and only one in China to lead the development of
down-hole tools applied for air/foam drilling, can provide series down-hole
motors for under-balanced drilling application.
